TETSUSABUBO WATANABE, OF NEW YORK, N. Y.

To all whom it may concern:

. Be it known that I, TETSUSABURO ,WATA- NABE, a subject of the Emperor of Japan, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Fountain-Pens, of which the following is a specification.

The invention relates to fountain pens, and consists in the combination with a suitable holder, or stock, of a cup-shaped inkholding reservoir supported on one end of the holder, an ordinary pen held in the holder so that it forms a cover for the open side of the reservoir, and a sliding sleeve on the holder constructed to retain the pen in reservoir-covering position and to be retractable to permit said pen to fall away by gravity from the reservoir, and so'release itself without requiring to be grasped by the fingers of the operator.

The invention further consists in the con struction whereby the reservoir is made adjustable with reference to the pen point, and the arrangement of the retracting spring for the sleeve within a metal thimble carried by the holder, as more particularly pointed out in the claim.

In the accompanying draWingsFigure 1 shows the manner of manipulating the device to release the pen. Fig. 2 is a perspective View of my device. Fig. 3 is a perspective view of the outer sliding sleeve. Fig. 4 is a perspective view of the spring holding thimble. Fig. 5 is a perspective view of the end of the pen-holder handle, to which the parts shown in Figs. 3 and 4 are applied. Fig. 6 shows the parts shown in Figs. 3, 4 and 5 assembled and in longitudinal section, with the pen and ink holding cup and supporting rod in elevation.

Similar numbers of reference indicate like parts.

Near the end of the pen-holder handle 1 is formed a circumferential groove 2. To said handle is applied the metal thimble 3, which is secured by turning the edge thereof inwardly to form a flange 4 which enters said groove, To facilitate this turning in, the thimble may be split at several points around said edge, as shown in Fi' 4. The outer end of the thimble is close and provided with a polygonal opening 5. In the wall of the thimble and extending from the FOUNTAIN-PEN.

13 over a part of its length to receive a nut 14. The end portion of said rod fits and may be frictionally held in an opening 15 in thehandle 1. A helical sprlng 16 is placed within the thimble 3.

In assembling the parts, the rod 12 is passed through the opening 5, and the nut 14 is adjusted on the threaded portion 13 .thereof so that when said rod is lnserted in the opening 15 in the handle, the fountain cup 10 will stand, as shown in Fig. 2, in proper relation to the pen 17. The spring 16 beln r put into the thimble, said thimble is secure in place on the handle by the flange 4, as alreadydescribed. The sleeve 8 is then placed over the thimble, with its lugs 9 entering the slots 6 and with the tongues 18 formed in its wall engaging a rib 19 on the holder handle. Finally, the pen 17 is inserted in the recess 7, and hence between the thimble and the sleeve 8. The lip 11 of the fountain cup then meets or very nearly meets the pen at a point near the nib thereof, and covers the usual opening 20 formed in the pen at the end of the slit therein while the pen forms a cover for the ink-holdin cup.

In operating the device, the pen is fipped in the ink in the ordinary way to fill the cup. Pressure on the nib in writing springs said nib outwardly from the lip 11, thus permitting the ink to flow from the cup downwardly to the pen point. In order to remove the pen without soiling the fingers of the operator, the handle 1 is grasped in one hand, and the sleeve 8 is slid along said handle, as shown in Fig. 1, until the pen releases itself from the recess 7 and falls from the pen-holder. The lugs 9 then travel in the slots 6 and engage the helical spring 16, which thus becomes compressed. After the pen is released, the spring 16 restores the sleeve 8 to its former position. The tongues 18 retain the sleeve 8 on the holder. hen the pen is removed, access to the interior of the fountain cup may be had for cleansing the same.
